Readible voice mail?

Hello I have Comcast Voice and sometimes messages go to my email.It will say,"you have a readable voice mail.Well one thing to read what someone has left for a message on the phone.But to get my name wrong is ridiculous.My brothe call me and he HI Charmaine Give me a call and I will talk to you later". But the message in my email reads,hi "Shannon give me a call I will talk to you later".My name is not Shannon and I doubt the audio was not clear for Comcast system to pick up from my AT&T phone.That is the second time my name was wrong.What is up with that?
